The luminescence of Pb 2+ in alkaline earth sulfates
The luminescence properties of CaSO 4:Pb 2+ (anhydrite), BaSO 4:Pb 2+, SrSO 4:Pb 2+ and PbSO 4 (all barite) are reported. Pb 2+-doped anhydrite shows Pb 2+ luminescence with a remarkably small Stokes shift to the emission. The barites, however, show emission with a much larger Stokes shift. It is ar...

Summary: | The luminescence properties of CaSO
4:Pb
2+ (anhydrite), BaSO
4:Pb
2+, SrSO
4:Pb
2+ and PbSO
4 (all barite) are reported. Pb
2+-doped anhydrite shows Pb
2+ luminescence with a remarkably small Stokes shift to the emission. The barites, however, show emission with a much larger Stokes shift. It is argued that the Pb
2+ luminescence in these compounds is not due to pure s ↔ p transitions on the Pb
2+ ion. |
